Properties of addition and multiplication
Key notes:
Associative property:
(g + h) + j = g + (h + j)
You can group the addends with brackets and get the same sum.
Associative property:
(k + m) + n = k + (m + n)
You can group the addends with brackets and get the same sum.
Learn with an example
Which property of addition is shown?
8 + (5 + 3) = (8 + 5) + 3
associative commutative
8 + (5 + 3) = (8 + 5) + 3
This equation shows the associative property. The grouping of the addends is changed.
Which property of addition is shown?
3 + 6 = 6 + 3
associative commutative
3 + 6 = 6 + 3
This equation shows the commutative property. The order of the addends is changed.
Which property of addition is shown?
5 + (1 + 8) = (5 + 1) + 8
associative commutative
5 + (1 + 8) = (5 + 1) + 8
This equation shows the associative property. The grouping of the addends is changed.
